Link state routing is the second family of routing protocols. While distance-vector routers use a distributed algorithm to compute their routing tables, link-state routing uses link-state routers to exchange messages that allow each router to learn the entire network topology.
In link-state routing protocols, each router possesses information about the complete network topology. Each router then independently calculates the best next hop from it for every possible destination in the network using local information of the topology.
Link State Routing: Drawbacks •LS more complex to implement than DV –Sequence numbers crucial to protect against stale announcements –Bringing up adjacencies –Maintains both link state database and routing table
CSE 123 – Lecture 12: Link-state Routing 24 Getting consistent routing information to all nodes E.g., all nodes having the same link-state database
Each router transmits a Link State Packet (LSP) on all links A neighboring router forwards out all links except incoming » Keep a copy locally; don’t forward previously-seen LSPs
This tutorial explains link state routing protocols. Learn what link state routing is and how it works in computer networks.
Intra vs. Inter-domain routing Link-state routing protocols CSE 123 – Lecture 15: Link-State Routing 2
Link state routing is a routing protocol where routers maintain a complete map of the network topology by exchanging link state information, enabling faster, more efficient path selection for data transmission.
Approaches to routing • Distance vector: – Distribute information about all nodes to my neighbors • Link state: – Distribute information about my neighbors to all nodes L4.7 Link State Routing • Idea: Each router learns the complete network topology and computes its own best paths • Two phase s: 1. 2. L4.8 Why link state routing?
A Link State Routing Protocol is an advanced type of dynamic routing protocol used in packet-switched networks to facilitate router-to-router data packet transfers.
